.SH "NAME"
zmq_plain \- clear\-text authentication
.SH "SYNOPSIS"
.sp
The PLAIN mechanism defines a simple username/password mechanism that lets a server authenticate a client\&. PLAIN makes no attempt at security or confidentiality\&. It is intended for use on internal networks where security requirements are low\&. The PLAIN mechanism is defined by this document: \fBhttp://rfc\&.zeromq\&.org/spec:24\fR\m\&.
.SH "USAGE"
.sp
To use PLAIN, the server shall set the ZMQ_PLAIN_SERVER option, and the client shall set the ZMQ_PLAIN_USERNAME and ZMQ_PLAIN_PASSWORD socket options\&. Which peer binds, and which connects, is not relevant\&.
